Biography

Radia was an Alpha-class ISO who first appeared during the Co-systems Administrator Installation Ceremony. Kevin Flynn in the ceremony picked her to be Co-systems Administrator with Original System Administrator Clu. She was eventually met by Anon and Quorra who informed her about Clu's deception. She eventually recognized Abraxas as her ISO friend Jalen, who was supposedly killed but was reprogrammed by Clu into a Virus. Radia was eventually derezzed by Abraxas, who attempted to infect her, but she instead derezzed in a brilliant display of light.

Trivia

Radia is very similar to Ophelia from the TRON: Betrayal comicbook. It is possible that this was intended to be the same character, yet became named differently due to development miscommunication between the game and comicbook.

Her name may have been inspired by Radia Perlman, a software developer.
